Students will create a food chain model and use it to describe the movement of matter among plants, animals, decomposers, and the environment. Resources include a detailed lesson plan, student handouts, pictures of a completed chain,...

[Free Registration/Login may be required to access all resource tools.] Based upon the way organisms acquire their energy students will understand how to group them as consumers, decomposers or producers.

Students learn about Abiotic and Biotic Factors and how they affect the ecosystem in which an animal might live in.

A video and a short multiple-choice quiz on the topic of ecosystems, covering biotic and abiotic factors, and the roles organisms play in an ecosystem.

Learn the difference between consumers and decomposers in the ecosystem.

Learn how scientists classify different types of organisms in an ecosystem or in a food chain by their role and function as either a producer, a consumer, or a decomposer. Then play a game that tests your understanding of these important...

Students investigate decomposers and the role of decomposers in maintaining the flow of nutrients in an environment. Students also learn how engineers use decomposers to help clean up wastes in a process known as bioremediation. This...

This lesson focuses on food chains in ecosystems, including levels of consumers, decomposers, and a list of common words used with food chains and their definitions. It also provides a link to an assessment.

This lesson focuses on the organization of an ecosystem. The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. It provides...

Being field scientists, students will explore a wooded area in their community and journal about their observations. Students will collect information about producers, consumers, and decomposers in the ecosystem. They will then construct...

How would you define an ecosystem? Check out this educational resource to learn more about the living and nonliving parts of different ecosystems.

A video and a short multiple-choice quiz on the nitrogen cycle and how it works in an ecosystem.

A video and a short multiple-choice quiz on food webs that explains the difference between food webs and food chains, and the relationships that exist between organisms.

A video and a short multiple-choice quiz on food chains that explains how energy flows through the chain, beginning with plants.

A module that explains what an ecosystem is and how energy and matter move through them. Students will look at the different roles of plants and animals and at ecological relationships in food chains and food webs.

Explore the food web in a coral reef with these illustration. Identify the consumers, producers, and decomposers that are located within this ecosystem. Site includes illustration exploring the different food chains as well as questions...

Omnivores, herbivores and carnivores are waiting for you. The food chain comes to life at this friendly site.

[Free Registration/Login may be required to access all resource tools.] Students will study how energy flows through an ecosystem and learn about photoautotrophs and chemoautotrophs, the role of decomposers, and of consumers.

This lesson focuses on the carbon cycle which shows how atoms of carbon can exist within different compounds at different times and be recycled between living organisms and the environment. It also provides a link to an assessment.

An ecosystem is composed of biotic factors of a community of living organisms interacting with one another which we can see in food chains/webs. These diverse organisms stay together because of the need of food. Population is referred to...

A lesson plan outlining activities for a science unit where students can learn about the relationships and the flow of energy within an ecosystem. These include predator and prey, hosts and parasites, and consumers, producers, and...
